Full title and description
ASTM A29/A29M-23 — Standard Specification for General Requirements for Steel Bars, Carbon and Alloy, Hot-Wrought. This standard establishes the common requirements that apply, unless otherwise specified, to a range of ASTM specifications covering hot‑rolled and cold‑finished carbon and alloy steel bars (chemical and heat analysis, mechanical testing, grain size, dimensional and marking requirements, and unit conventions).
Abstract
A29/A29M-23 provides general delivery and quality requirements for carbon and alloy steel bars that are hot‑wrought or cold‑finished. It is intended to be referenced by individual material specifications and supplies overarching rules on units (inch‑pound and SI), rounding procedures, testing and inspection, chemical/heat analysis, mechanical tests, grain size, marking, and the precedence of purchase order and individual specifications where conflicts exist.

Scope
This specification covers a group of common requirements that, unless otherwise specified in the purchase order or in an individual specification, apply to carbon and alloy steel bars produced to a range of ASTM material specifications (hot‑rolled and cold‑finished grades). It addresses required chemical and heat analyses for selected grades, mechanical testing, grain size where applicable, marking and identification, unit systems (inch‑pound and SI treated as separate standards), and rules for resolving conflicts among purchase orders, individual specifications, and this general specification.
Key topics and requirements
- Applicability to multiple ASTM bar specifications (lists referenced standards that invoke A29/A29M).
- Heat and product chemical analysis requirements for specified carbon and alloy grades (C, Mn, P, S and additional alloying elements where called for).
- Mechanical testing and acceptance criteria required by referenced individual specifications.
- Grain size testing where specified and other metallurgical requirements.
- Dimensional conventions, dual unit usage (inch‑pound and SI treated independently), and rounding procedures per Practice E29.
- Ordering and inspection conventions including precedence of purchase order, individual specification, then this general specification in case of conflict.
Typical use and users
Used by steel producers (mills), material testing laboratories, quality managers, procuring engineers, fabricators, and purchasers specifying carbon and alloy steel bars for structural, mechanical, spring, pressure‑part, and general engineering applications. It is also used by government agencies and defense contractors when referenced by individual material specifications.
Related standards
A29/A29M is a general requirements document referenced by and related to numerous ASTM bar specifications, for example A108, A311/A311M, A321, A322, A304, A434/A434M, A499, A575, A576, A663/A663M, A675/A675M, A689, A696, A739 and others; it also references practices such as E29 (rounding procedures) and E112 (grain size). These related specifications define the specific chemical, mechanical, and dimensional requirements for particular bar grades.
